Find the correlation.. X Y cDdEe AaBb pacing Headi 5 3 EX- ZY- EX-= EXY= 6.4. Can the following variables be correlated and, if so. would you expect the correlation to be positive or negative? a. Height and weight of adults b. Weight of first graders and weight of fifth graders C. Average daily temperature and cost of heating a home d. IQ and reading comprehension e. The first and second quiz scores of students in two sections of General Biology f. The section 1 scores and the section 2 scores of students in General Biology on the first quiz *6.5. This problem is based on data published in 1903 by Karl Pearson and Alice Lee. In the original article, 1376 pairs of father-daughter heights were analyzed. The scores here produce the same means and the same correlation coefficient that Pearson and Lee obtained. For these data, draw a scatterplot and calculate r by both the raw-score formula and the blanched formula. Father's height, X (in.) 69 67 65 63 73 Daughter's height, Y (in.) 62 65 64 631 58 63 *6.6. The Wechsler Adult Intelligence Scale (WAIS) is an individually administered test that takes over an hour. The Wonderlic Personnel Test can be administered to groups of any size in 15 minutes. X and Y represent scores on the two tests. Summary statistics from a representative sample of 21 adults were EX - 2205, EY = 2163, EX- = 235.800. EY = 227,200, EXY = 231,100. Computer and write an interpretation about using the Wonderlic rather than the WAIS. 6.19. In problem 6.5, the father-daughter height data, you found r = .513. a. Compute the regression coefficients a and b. b. Use your scatterplot from problem 6.5 and draw the regression line. 6.20. In problem 6.6, the two different intelligence tests with the WAIS test as X and the Wonderlic as Y, you computed a. Compute a and b. b. What Wonderlic score would you predict for a person who scored 130 on the WAIS
